We have nearly every part for a variety of life jackets in stock

Lifejacket Spares

United Molders

Mk 5 Auto Cartridge - These tend to be black with green bottom and a date stamped on the outside. 

Pro Sensor Auto Cartridge - These are again black but also have a black bottom. 

Retaining clips - These are normally green and clip to the operating head of the life jacket and prevent accidental pulling of the life jacket.

Halkey Roberts

Auto Bobbin - These are yellow and can be found inside the clear 'bowl' at the bottom of the operating head. These have a manufacturing date on them NOT an expiry date

End cap - These suffer from damage quite a bit so we offer replacements

Cylinder seal - This type of operating head require a new cylinder seal everytime the cylinder is removed and at least every two years


A1 - These are the replacement auto hydrostatic heads. These are slowly being replaced with the new ISO version below

MA1 - New version of the above. These can be identified by the yellow pull handle. The older version has the red handle

Back plates - These are different for each of the above heads. The MA1 now requires the cylinder to be glued in place. This is completed at our workshops before dispatched as a spare part
